NOTES

Input circuit

Input Terminals of pin (5) and (6) (TA7291P) are all

high active type and have a hysteresis of 0.7 V (typ.),

3 A (typ.) of source mode input current is required.

Output circuit

Output voltage is controlled by Vrefvoltage.

Relationship between VOUT and Vrefis

VOUT= VBE ( 0.7) + Vref

Vrefterminal required to connect to VS terminal for

stable operation in case of no requirement of VOUT

control.

APPLICATION CIRCUIT

Note 1: Experiment to find the optimum capacitor valve.

Note 2: To protect against excess current, current limitation resistor R should be inserted where necessary.

NOTES

l Be careful when switching the input because rush current may occur.

When switching, stop mode should be entered or current limitation resister R should be inserted.

l The IC functions cannot be guaranteed when turning power on of off.

Before using the IC for application, check that there are no problems.

l Utmost care is necessary in the design of the output line, VS, VCC and GND line since IC may be destroyed dueto shortcircuit between outputs, air contamination fault, or fault by improper grounding.
